FIELD: oil production. SUBSTANCE: device has a pickup of the force exerted by the drive of a pump, pulse generator, controllable inverter, memory unit, and governor of the speed of the pump drive. The force pickup is a frequency or analog type one. The pulse generator is made up as microswitches arranged at the top and bottom points of movement of the rod of the pump drive. The integrator is made up as an operation amplifier of the pulse counter. The speed governor may be made up as a frequency type controller that allows a speed corresponding to a work done to be determined. EFFECT: enhanced reliability. 3 dwg
